Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610352, here are decompositions:

13 + 31610339 = 31610352
19 + 31610333 = 31610352
61 + 31610291 = 31610352
73 + 31610279 = 31610352
83 + 31610269 = 31610352
139 + 31610213 = 31610352
181 + 31610171 = 31610352
211 + 31610141 = 31610352

Showing the first eight; more decompositions exist.
